I will add that I've been looking for service since May. A couple local watchmakers turned down the repair sure to complexity and availability of parts, if needed. I do appreciate them being upfront about this.

: I recently purchased a 1972 Autavia 1163 V.

: Appears to be in good condition with few case dings and nice bezel
: with maybe a bit of fading. I believe unpolished case. Crystal
: has quite a few scratches, but not cracked. Lume is intact with
: slight yellowing.
: Watch functions well, although I believe it may run a bit slow -
: maybe a minute per day. Chrono function and pushers work as
: expected.
: The story behind the watch was the owner died in 1983 and the widow
: gifted it, along with other unique items, to a family friend
: also in 1983. The watch remained unworn and placed in a box
: since 1983 with an occasional viewing.
: My goal is to keep the watch and wear on occasion in rotation with
: other watches.
: I do have concern about old seals letting in water/humidity and
: potential dried out lube. I've read that old watches like this
: should be serviced to prevent premature wear.

: I am looking for recommendations (preferably USA-based) to perform
: service on the watch with access to any potential parts. Maybe
: replace or refresh the crystal, but keep the overall vintage
: look in-tact. Of course, I would listen to the advice of the
: watchmaker, as they are the expert. I am located in Missouri.

: I searched the forums with recommendations for Craig Bergsma at
: Chronodeco. Unfortunately, he is no longer taking on new
: customers.
: Any other recommendations?

: Thank you.
